Abstract: The present invention relates to real time discharging droplet compensating apparatus and method capable of compensating a discharging degree in real time by feeding-back drop information. To this end, the present invention provides a real time discharging droplet compensating apparatus which is configured by including a discharge control unit controlling the driving of an inkjet head; and a drop measurement unit provided below a substrate to measure drop information of a droplet to be discharged on the substrate and feed-back the measured drop information to the drop measurement unit, wherein the discharge control unit compensates a nozzle waveform of discharging the droplet by using the drop information. Therefore, according to the present invention, the position, size, and volume information of the drop are measured at the same time to be fed-back to the inkjet head unit in real time, thereby acquiring drop information without movement of a separate head unit.

Abstract: An ink tank for a liquid chemical discharging apparatus capable of preventing equipment failure and improving durability by preventing scattering and backflow of a liquid chemical. To this end, the present invention provides an ink tank for a liquid chemical discharging apparatus including: a liquid chemical receiving portion in which a liquid chemical is stored; a liquid chemical discharge port supplying the liquid chemical to an inkjet head; a pressure control port for controlling pressure of the liquid chemical receiving portion; and a partition wall which is provided in the liquid chemical receiving portion to partition the liquid chemical receiving portion. According to the present invention, it is possible to prevent contamination due to a liquid chemical by suppressing the liquid chemical from sloshing and improve durability of an ink tank by preventing the liquid chemical contained therein from flowing backward out of the ink tank.
